Accumulation of CH 4 (in nmol) in the headspace of the incubation bottles as a function of time. a) is the concentration of CH4 in the bottles containing 2.2 mM bicarbonate buffer and the accumulation rates in mol/m2/s and b) is the concentration of CH4 in the bottles containing only Milli-Q water and the accumulation rates in mol/m2/s. All values are after subtracted control values.
